The 21st District encompasses 16 communities in Morris, Somerset, and Union counties: Berkeley Heights, Bernards, Chatham Borough, Cranford, Far Hills, Garwood, Kenilworth, Long Hill, Mountainside, New Providence, Roselle Park, Springfield, Summit, Warren, Watchung, and Westfield.
Voter registration is almost evenly split between the parties, with about 28 percent each, but the unaffiliated voters traditionally swing the results to the “red” side of the ballot.
The entire GOP contingent of representatives is back on the ballot: Sen. Thomas Kean Jr. of Westfield, Assemblyman Jon Bramnick of Westfield, who is the Republican leader in the lower house, and Assemblywoman Nancy Munoz of Summit.
The Democratic slate includes the candidates who were unsuccessful at Assembly runs two years ago — Jill Anne Lazare of Summit for Senate and David Barnett of Springfield for Assembly. Lacey Rzeszowski of Summit is seeking the other Assembly spot.
